' ENAMELED IRON BATH-TUB.

Specification of Letters Patent.

Applicationled March 23, 1911. Serial No. 616,309.

To all whom t may concern Be it known that I, JOHN CLIFFORD, a citizenof the lUnited States, residing im Chicago, inthe county of Cook andState of Illinois, haveVinvented va new and useful Improvement inEnameled Iron Bath-Tubs, of which the following' is a specification.

My invention relates to improvements in enameled iron bath tubs.Heretofore, enameled iron bath tubs have only had an enamcled orvitreous coating uponfthe inside, thetubs, however, being usuallyfurnished with a rolled rim and with the enameled coating on the insideof the tub extending continuouslyover"the external surface of the rolledrim, the interior surface of the rolled rim and the exterior surface ofthe tub being unprotected or simply covered with white paint, which isneither durable nor sanitary, and soon becomes very unsightly,especially at the exposed side or exposed end or ends of the'tb. And asthe tubs and their rolled rims arealways made with rounded corners,crevices or confined openspaces are necessarily left or formed betweenthe back side of thetub and the'wall and between one lor both ends ofthe tub and the wall, and also under the tub ,for collectin of dirt andlitter where itjcannot be readily removed or kept clean, thus renderingthe installment as a Whole objectionableland far from sanitary. It isractically impossiblel to enamel an iron bath) tub simultaneously'bothupon its Jinside and outside surfaces, and if it were attempted toenamel it upon the inside first, and then subsequently enamel it uponthe outside, the inside enamel coating would be cracked and destroyed inthe heatlng step of the sepond enameling operation. And even if an ironbath tub could be `enameled upon both its inside and outside surfaceswithout such difficulty and expense as to render -it impractical,- thefixture would still have the objection of unsanitariness' on account ofthe confined spaces left between the tub and the 4fioor and side and endwalls of the building against which the tub is installed.

The object of my invention is to provide an improvedconstruction ofenameled .iron bath tub which will be perfectly sanitary, which may beinstalled in a bath room with one, two or more of its upright sides orends exposed as may, `be required and without leaving or forming anyconfined spaces or crevices between the other sides or ends of Myinvention consists in the means I have devised and employ to practicallyaccomplish this object or result, the same consisting essentially in anenamel iron tub, provided with a straight edged, square cornered.adapted at'one or more of its sides or ends to form a tightjoint withthe wall of the vroom against which the tub is installed, and separatepiece removable straight edged andl square cornered enameled iron skirtmembers 'fitting under the straight edged rim of the'tub and extendingto theioorj and -inclosing the tub at its exposed'side or exposed sideand end or exposed side and ends, as the case may be, the straight,horizontal lower edges of the skirt members formin tight joints with thetile, cement or other oor of the room, and the straight, upright edgesof the skirt member or members forming tight joints with the tile or j Iother wall of the bath room and the skirt ymembers having at the outerorex osed In the accompanying drawing forming a.

part of this specification, Figure 1 is a plan view of an enameled ironbath tub embodying my invention, showing a portion of one ofthe uprightwalls of a bath room in section. Fig. 2 is a vertical, longitudinalsec-l tion on line 2-2 of Fig. 1. Fig. 3 is an upright, cross section online 3 3 of Fig. 1. Fig. Lis a detail elevationy of the side skirtmember; Fi 5 is a detail elevation of one of the end sk1rt members. Fig.6 is a detail, partial, horizontal section on line 6-6 of Fig. 2. Fig. 7isa? detail, vertical, longitudinal section showing a modification inlLO one end of the tub is exposed. Fig. 9 is a plan view illustratinganother modifica-tion,

wherein4 the fixtures or water supply pipes are located within the wallof the bath room. Fig. is afplan view, partly in horizontal section,illustrating a further modification i -in which but one sid-ei ofl thetub is exposed,

both ends and one side being Vjoined to the upright walls of the room.

In the drawing, 1 represents an yenameled iron bath tub having thecustomary enamel coating 2 upon its inside and upon the outer surface orits rim 3. The 'rim 3 of the tub is straight edged and square corneredand has one or more of its straight, horizontal edges 4L adapted to forma tight joint with the uphight cement or tile wall 5 of the bath room, 1andone or more of its other edges as 6, 7 and 8 adapted for junctionwith the separate piece removable enameled iron skirt members 9, 10, 11,allof which have an enamel coating 12 upon their outer surfaces. Thestraight edged and square cornered rim 3 of the bath vtub is providedwith a marginal `depending iange A13, .the inner face 14 of which iangeis upright and straight to form a snug closejoint with the straight,horizontal-upper edges or joint flanges 15 with which each of the skirtmembers is provided. Each of the skirt membersis also furnished with astraight, lower, horizontal edge 16 to form a squarejoint with thecement tile or other floor 17 of 1e bath room,

the joint flange or edge 16be` g preferably set into the masonry of thefloor, as will be readily understood from Figs. 2, 3 and 4 of thedrawing. Eachof the end skirt mem,- bers 7 8 is also provided at eachend with van upright, straight edge or flange 18 adapted to form tightclose joints with the cement, tile or other upright wall 5 of the bathroom or' with the front or sidev skirt member 9.

The rim 3 of the tub is provided with a plurality of inclined faced orwedging integral lugs 2O on the under side thereof for engagement withcorresponding horizontally projecting ianges 21 with which the re ovableskirt members 9, 10, 11 are provided, the wedging lugs 20 and flanges 21in connection with the rim-flange 13, thus serving-to lock the skirtmembers 9, 10, 11

rigidly imposition under the rim of the bath. tub and within themarginal depending flange 13 of said rim. The separate piece skirtmembers 9, 10, 11 arepreferably furynished with {ian-ges 21 at -boththeiru'pperv and lower horizontal. edgesso that Jthe skirtL :membersmaybe placed either side up ifde- Iixtures'or 'water supply andwvfastepipes-24c j l-a side, as -straight si e edge and rone separate end edgeof thetub rim 3b forms fa tight joint with- ;siredi, and as the a'ng'esalso serve to' strengthen and stifl'en the skirt members againstwarping. The side skirt member 9 is provided at its upright ends withcurved flanges 22 which embrace the straight edges or `flanges 18 of theend skirt memberslO, 11. The side skirt member 9 is alsolprovided with aplurality of wedge faced lugs 23 for engagement with the straight edgesor flanges 18 of theend skirt members 10, 11 and thus serve to lock! theend skirt members to the side skirt member and form a strong and rigidupright corner at the junction of the side and end skirt members. Theenameled iron removable skirt members 9, 10, 11 are thus all held firmlyand rigidly in position without the necessity of any screws or formingany bolt holes through the enamel coating of the skirt members. As thecurved corner fianges 22 of the side or front skirt member 9 are turnedtoward the wall, the joint between the extreme edges of the curvedlianges 22 and the straight edged joint iianges 18 of the end skirtmembers 10, lliis turned toward the wall, and not noticeable from theroom so that the appearance of the bath tub installment as a whole isthe same as though the bath tub, its rim and the skirt members were allin one solid piece. This gives the fixture asa whole a very neatappearance in connection with the depending marginal flanges 14: of thebath tub rim 3`which embrace and conceal the -upper straight horizontaledges of the removable separate piece skirt members.

The water supply and waste izrtures or pipes 24 may be upon the outsideof one of and 2, in which case the end skirt member 11 is provided withopenings 25 andbosses 26 to receive the horizontal pipes 27 which arefurnished with caps or flanges 29 to give a neat finish at the pointswhere the horizontal pipes pass through the enameled iron end skirtmember. If preferred, as illustrated in Fig. 7, the water' and wastefixtures 24:a may be located between the upright end wall of the bathtub at the outlet end and the enameled iron end skirt member 11n. Insuch case, the rim of the tub at the outlet end thereof is increased inwidth as indicated at 3a. in the drawing.

In the modification illustrated in Fig. 8,

the construction is the same as shown in Figs. 1,2 and 3,.excepting thatthe tub is exposed and has skirt members at only one end and one sideinstead of at two ends and saown in Fig. l. In Fig. 8, one
